We’re really struggling with boys sleep (he’s 3 now) at the moment and feeling pretty exhausted. For the last 6 weeks he hasn’t gone more than about 3 consecutive nights without waking in the night. Before this he was sleeping well, so this feels like a huge regression compared to anything we’ve dealt with before. We’ve tried quite a few things, including later bedtimes in case he was getting too much sleep, reward charts/treat jar for a “big sleep”, talking about how his friends have big sleeps, using the Groclock so he knows it’s still night time, making sure he’s had enough to eat before bed etc, but nothing really seems to be helping. We’re not fully sure what’s causing the wake ups. It could potentially be bad dreams, but when we go in he doesn’t seem terrified, more upset and unsettled. We can hear him on the monitor getting distressed, but not screaming. For context, he’s usually asleep around 7pm. He doesn’t nap during the day. The wake ups are normally around 2/3am and it’s usually once a night, although occasionally more than that. At bedtime his routine is still falling asleep on us in the chair before we transfer him into his cot bed. We’re wondering whether introducing a “big boy bed” and changing the bedtime approach might help? For example, after bath time getting him to climb into bed himself and reading stories there instead, and potentially removing the chair from the room. Our only worry is then him waking up and escaping from the room. We end up sitting with him on our knee in the chair for quite a while before trying to transfer him back into bed. Sometimes that works after 30 minutes or so, but other times she ends up lying next to him on the floor for up to 2 hours trying to settle him. We’ve also tried the more brief reassurance approach where we go in every few minutes, reassure him briefly, then leave again, but when we tried that it also seemed to drag on for hours without much improvement, although maybe we need to persevere with this more consistently? He’s still in his sleeping bag and cot bed and has never attempted to climb out. Up until recently he’s been a good sleeper. With our baby also not sleeping brilliantly at 9 months, we’re both just feeling pretty broken by it all at the moment and not really sure what the best approach is anymore, so would really appreciate any advice. Help!
